Guerrero Fernandez Winery
Guerrero Fernandez Family Winery produces limited quantities of exceptional handcrafted boutique wines using traditional winemaking techniques. Throughout the process we pour our heart and soul into achieving a balance amongst the soil, fruit and our love and passion for winemaking. Our mission is to produce wines of the highest quality making justice to the fruit.

We believe that a great wine starts in the vine. Ample selection of blends and single varietals, aged for an average of 36 months in French Oak. Our wines are well balanced with soft tannings and an elegant velvety finish. Appointments for tastings are recommended, but we always try to accommodate all our future club members.

Amazing winery. Olga and Martin make you feel like part of the family when you come in... so much so that we joined the wine club. They are very attentive and really help you find wines you enjoy. There are many different kinds of wine to try... I recommend the Dominic!!!

This family owned business is incredible. From the welcome as you arrive, to the aromas of the wines, to the stories behind each bottle...we could not have asked for a better afternoon. Olga and Martin made it a point to visit with their guests....they instantly made a connection with us by welcoming us to their winery as if it were their home. The wine is excellent and the presentation is elegant. There was no pressure to join a club or to buy wine...it was just a magnificent experience that left us wanting to more. We will be back. Excellent!

Amazing story and top shelf wines. Olga spent an hour and a half with us as we sampled whites and reds. A great couple that I would gladly have dinner with. Made our second visit to the area memorable. Love their wines.

Great wines from fantastic winemakers who have a passion for producing world-class red varietals. We found their wines after a week long visit to Napa and Sonoma that included a number of “invitation/cult” only wineries and Guerrero Fernandez is frankly better at a fraction of the cost!

Lovely, down-to-earth family owned and operated winery. If you're tired of the pretentious tasting room, look no further. The winemaker has something for most everyone; from the light, jammy l, fruit forward to robust reds. Each wine label has a great family story.

Amazing husband/wife winery with decades of experience. Literally, all of their wines are so flavorful and balanced and ready to drink since they are pre aged.

This wine is spectacular. The Cabernet Sauvignon was mouthwatering. Olga and Martin were generous with their pours and fantastic hosts. Bought 5 different wines from them. Highly recommend you check them out.

Wow - this tasting room was a delightful, unexpected surprise. Located in Windsor's Artisan Alley (aka Beverage District), this mom & pop shop is making/pour some of the best reds around town. No joke.

Don't come here expecting a fancy schmancy tasting lounge. This is a no-frills, industrial kind of space that can accommodate roughly 10 people maximum. So be sure to call in advance to schedule an tasting. The wines are produced by a lovely husband/wife team (Olga Fernandez and Martin Guerrero). He's more of a back-of-the-house guy/winemaker. And she is definitely a charming

STOP AT THIS TASTING ROOM! This place is such a diamond in the rough! Olga and Martin are absolutely incredible people with even more incredible stories. Olga runs marathons and dominates! There is a whole wall dedicated to all of her amazing achievements. Not only were the owners amazing but their wine was some of the best I have had in the area! We stumbled upon this place after being at an event nearby and we are so glad we did! They asked us what kind of wine we liked and we were a mixed bag but all agreed we like rose. They didn't have a rose quite ready yet but they allowed us to try

We stumbled upon this hidden little gem in Windsor yesterday and decided to go inside and do a tasting. We got a very personalized experience and tour of the facility. You can feel the passion that the amazing owners, Olga Fernandez and Martin Guerrero, have about making their wines. It shows in the flavor of their wines. Although their Zinfindels- especially the one in French Oak - were my favorite, I also really enjoyed their Boy and Girl Labels, particularly the Scarlett, Dominic, and Dimitri which were named after their niece and grandsons.

We had such a lovely visit with Olga and Martin

A truly excellent small family winery; very interesting wines -- particularly the red blends -- along with a warm reception make this a great place to visit. Don't let the location in a Windsor industrial area put you off -- these are top notch Sonoma county wines at reasonable prices.

What a hidden gem! The husband and wife are so sweet and nice. We only decided to stop by because the owner of the brewery, St. Florian's on the next block recommended it for free tastings. We even got to try from the barrel. Great for red wine lovers. They don't have their own vineyard so they source out their grapes. We walked out with 4 bottles, bottles ranged from $35-$85.

Great customer service with so much knowledge. The variety of wines that they have very in years which is rare! If you are in the county you don't want to miss them.
Martin and Olga make an incredible team.
Well earned 5 stars!
